Since the RAND Health Insurance Experiment, RAND Health has led the way in efforts to understand the links between physician payment, quality of care, and system cost.
RAND piloted proposed G-codes to determine whether doctors understood and correctly applied the codes. Using vignettes to test coding accuracy, researchers made recommendations for refining coding instructions.
The New Jersey state legislature is debating proposals to limit payments for involuntary out-of-network care. Researchers analyzed the role of these payments in hospitals' financial performance and simulated the effect of policies limiting such payments.
